.net - How to read weight from scale using ethernet connection -

-

hi first post please bare me.

i have mettler toledo xs32000l scale , trying read weight via ethernet connection , vb.net (2010) application. have found plenty of information/code serial(com) connection nothing ethernet connection.

communication mode: client & server remote host address: 192.168.0.2. remote host port number: 8001 local server port number: 8000 (scale ip: 192.168.0.1)

i able ping scale reply. have tried using hyperterminal no luck. appreciated, , post can many others come. thanks!

alright - despite criticism, going post solution after hours of researching. created tcp client , modified settings (ip, port, etc.) helps future programmers!

imports system.net.sockets  public class form1  private sub form1_load(byval sender system.object, byval e system.eventargs) handles mybase.load     call connect("192.168.0.1", "s" & vbcrlf) end sub  shared sub connect(byval server [string], byval message [string])     try         ' create tcpclient.          ' note, client work need have tcpserver           ' connected same address specified server, port          ' combination.          dim port int32 = 8000         dim client new tcpclient(server, port)          ' translate passed message ascii , store byte array.          dim data [byte]() = system.text.encoding.ascii.getbytes(message)          ' client stream reading , writing.          '  stream stream = client.getstream();          dim stream networkstream = client.getstream()          ' send message connected tcpserver.          stream.write(data, 0, data.length)          'console.writeline("sent: {0}", message)         msgbox("sent: {0} " & message)         ' receive tcpserver.response.          ' buffer store response bytes.         data = new [byte](256) {}          ' string store response ascii representation.          dim responsedata [string] = [string].empty          ' read first batch of tcpserver response bytes.          dim bytes int32 = stream.read(data, 0, data.length)         responsedata = system.text.encoding.ascii.getstring(data, 0, bytes)         'console.writeline("received: {0}", responsedata)         msgbox("received: {0} " & responsedata)          ' close everything.         stream.close()         client.close()     catch e argumentnullexception         'console.writeline("argumentnullexception: {0}", e)         msgbox("argumentnullexception: {0}" & e.message)     catch e socketexception         'console.writeline("socketexception: {0}", e)         msgbox("socketexception: {0}" & e.message)     end try      msgbox("got point in code")      'console.writeline(controlchars.cr + " press enter continue...")

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
